Title:
IMPROVED CHEMICAL MANAGEMENT FOR SWIMMING POOLS
Document Type and Number:
WIPO Patent Application WO/2015/179919
Kind Code:
A8
Abstract:
A system for electric pH control of saltwater swimming pools, comprising: (a) a pump-assisted circuit for circulating saltwater to and from a swimming pool; (b) means for determining the pH of the saltwater; (c) a pH control cell having at least one pair of electrodes arranged for electrolytically creating an alkaline and an acidic chemical, the cell comprising a water flow-through compartment and a species separation compartment, the compartments being separated by a separator structure; (d) a drainage structure; and (e) a controller functionally operative to (i) compare the pH determined or sensed with a desired pH value, (ii) apply an electric potential across the electrodes of the cell and control one or both of the potential and electric current supplied to the electrodes as a function of the pH comparison and (iii) regulate drainage of an alkaline or acidic species which has been electrolytically generated.
